Ring 2 giving motion alerts with people only turned on

In the last two or so weeks our ring 2 has been going crazy with false motion alerts when nothing is there, including bugs, cars, trees, or plants. I've had to turn off notifications overnight because they REALLY go off then. In a desperate attempt to stop the constant alerts I turned on People Only mode. In spite of this I am getting multiple 'unverified motion' alerts every hour. I loved this doorbell when I get it and it worked great for over a year but all of the sudden it's driving me crazy. Here are the 5 alerts I've gotten so far today (it's only noon here). I can't bring the field in any tighter at this point and it's only tracking one field which faces the porch wall. Please help!
